I'm currently doing only push ups for my chest, but i want to do my shoulders and back as well, are there any exercises , where dumbbells are not included, that could help me get in shape?

Instead of being a faggot telling you to get a gym membership like everyone else in here because I don't know what situation you're in and why you won't/can't have access to a gym membership or dumbbells, I'll give you a few exercises.

Superman can be quite good for your lower back, for your triceps you could do dips, for your lats and honestly most of your upper body, pull ups are very good, you could also do Curls and Shrugs for your Biceps and Traps if you've got something you can use, like a milk jug filled with pebbles or something if you want to get creative.

Crunches could be good for your abs, you also have lunges and squats for your legs.

It's all I can think of right now though if you can and have the money for a gym membership I highly suggest you buy one. Also make sure to work your legs too unless you want to become McChickenlegs Douchemaster.

If i see the word crunches on this forum again i am going to shit myself.

Now, productive advice was already given so ill simplify it for you even more so u can make up ur own shit; you pull something u use back. You push something u use chest triceps shoulders. You hold something its traps and forearms. You go down with it its legs.

There are a lot of stuff you can do. You can build yourself up to a l-sit for your shoulders, chest, triceps and of course your abdominal. You can learn handstands and from there on do handstand presses for a lot of muscle groups and as you advance you can basically train each trainable muscle in your body.

I dont go to a normal gym, but a boxing gym, it cost me about 200-300$ a year and its 2 day a week for novice level and 3 for more advanced, its 2 hour of intensive excersise each time, plus boxing training, and competition against other fighter in my country. Nice and cheap, but not if you want to get bulked up, but it wont the same from a gym to other.
